Glasses are often the first choice when it comes to correcting a visual impairment. But despite the diversity and modern features, many customers are more and more often looking to contact lenses. Amongst the most important reasons are that flexible monthly and daily lenses from CooperVision or Acuvue are all but invisible and therefore don’t alter your outward appearance – unlike glasses. Besides which, contact lenses are significantly more practical in many situations and can correct almost all visual problems. Next to short and long-sightedness, presbyopia is one of the most often reasons for their use.
